In this videoconference talk from 19 February 2021, Ajahn Anan discusses Magha Puja, a holiday falling on February 26 this year.

This is the day the Lord Buddha gave the Ovada Patimokkha (which can be roughly translated as "Teaching on the Entryway to Liberation) to a group of 1,250 bhikkhus who had come together without any prior arrangement on the full moon day of the third lunar month (the Magha month), who were all fully enlightened with psychic abilities, and who were ordained by the Buddha himself. The Ovada Patimokkha contains the heart of the Buddha's teachings, which is to refrain from evil, do good, and purify the mind.
